Hydrocarbons as polyurethane blowing agents in domestic appliances.

Author(s) : WENNING U. G.

Summary

The necessity to replace CFCs in domestic appliances has led to the development of polyurethane foams with HCFCs (eg 141b), HFCs (eg 134a) and hydrocarbons as blowing agents. In Europe HCFCs are under attack because of their ozone depletion potential, whereas HFCs still have a certain global warming potential. In order to avoid public discussions and intermediate solutions there is a strong tendency to use hydrocarbons in the insulation of refrigerators-freezers. The slightly higher k-factor and the risks of flammability associated with hydrocarbons have to be accepted.
